To all whom it may concern:

RE'GULATING DEVICE.

Specification of Letters Patent.

Patented Aug. 25, 1914.

Application filed March 25, 1913. Serial No. 756,731.

Be it known that I, JOEL M. SnrzEn, a

citizen of the United States, residing at St.

particularly to be inserted 5 is the sleeve Paul, in the county of Ramsey and State of Minnesota, have invented certain newand useful Improvements in Regulating Devices, of which the following is a specification.

My invention relates to improvements in gas pressure regulating devices adapted in the gas pipe between the meter and point of consumption.

To this end the invention consists in the features of construction, combination, and arrangement of parts hereinafter described and claimed.

In the accompanying drawings forming part of this specification, Figure l represents an end View of a section of gas pipe used between the meter and point of consiunption; Fig. 2 is a section on line a-m of Fig. 1 showing the pipe partly in elevation; Fig. 3 is a section taken at right angles with Fig. 2; and Fig. 4 is a detail view, broken away, of an actuating handle for the regulator.

Referring to the drawings, A represents a section of gas pipe forming part of the piping between the meter and burner. Centrally supported in the meter end of the pipe, as by a cross bar 2, is a central rod 3, upon the free end of which are supported the opposed concaved plates 4: and 5. Slidable within the pipebeyond the plates 4 and 6 formed with a centrally restricted opening 7 the opening 7 upon the lower side merging into a gradually enlargmg inlet opening 8, and upon the opposite side of the sleeve merging into a gradually enlarging outlet opening 9. The downwardly curved plate 4 seats within the bottom of the inlet opening 8 and the smaller upwardly curved plate seats against a seat 14 in the side wall of the inlet opening 8. The sleeve 6 is adjustable through the medium of a crank shaft 10 journaled in the pipe, the crank shaft being connected by a link 11 with the sleeve. One end of the crank shaft supports a handle 12 011 the exterior of the pipe, the handle being in the form of an indicator working in connection with a gage 13 whereby to indicate the position of the sleeve within the pipe.

By means of the oppositely concaved plates a more efiective seating thereof within the sleeve is secured.

By means of the adjusting mechanism for the sleeve the gas can be shut off to any desired degree.

I claim as my invention:

In combination with a gas pipe, a concave spreader plate having a central fixed support therein, a sleeve slidably supported within the pipe and formed with a restricted opening, said opening being enlarged toward said spreader plate suflicient to receive the same at its enlarged end.

In testimony whereof I aflix my signature in presence of two witnesses.

JOEL M. SETZER.
